Latent Impression Recovery & Examination

A fingerprint is an impression left by the friction ridges of a human finger. A print from the foot can also leave an impression of friction ridges. A friction ridge is a raised portion of the epidermis on the fingers and toes (digits), the palm of the hand or the sole of the foot, consisting of one or more connected ridge units of friction ridge skin.

In forensic science the term latent print means any chance or accidental impression left by friction ridge skin on a surface, regardless of whether it is visible or invisible at the time of deposition. Electronic, chemical and physical processing techniques permit visualization of invisible latent print residues whether they are from natural sweat on the skin or from a contaminant.

Larsen Forensics uses not only the traditional recovery techniques in locating and collecting of latent prints but has in its forensics arsenal the latest latent recovery equipment currently used by the Federal Bureau of Investigation Evidence Response Teams. Larsen Forensics utilizes two certified latent fingerprint examiners when conducting latent comparisons and making identifications.
